what you get booting |
Someone brought me an imac model a1058 system that would not boot. if left alone, you would get the folder "?" message on the screen. The hard drive is bad. I used a program called TransMac to try to access the drive, and it cannot do so. (you can hear odd seek noise from the drive)
Replaced the drive with a new 160GB drive. I didn't think I had to, but I used that TransMac program to format the drive for mac, and installed it. No problem. Put the Applecare disc in, hold C on power up, and you can get the apple logo with a spinning cursor below, and that's it. Goes nowhere from there. The disc DOES have scratches, so I again used the TransMac software to create a disc image of this CD (no errors) and burned the image to a new CD. Same result.
Inspection of the board shows one swollen/leaking capacitor. Now, I know bad caps can cause all sorts of issues, but does this behavior (no booting from CD) point to this? The unit's not locked up, the spinning cursor just spins. Could this be a faulty CD as well? Given the fact the original is scratched?
I've done some looking, and it appears these models are prone to failure, but I thought I would utilize this forum to ask a second/third/etc opinion.
Options? Ideas?
Thanks for any info. |

| You probably have a logic board (main board) failure on the disk bus. Swollen capacitor could cause this.
However, I believe Apple had a out-of-warranty repair for capacitor problems, so it might be worth calling them.

All iMac G5s are now classified as vintage, meaning Apple won't directly repair them as no parts are being made. Local providers in your area *may* be able to tackle a capacitor repair, but it's case-by-case on availability. The soldering job to replace caps isn't too complicated for an experienced solderer who works with surface mount electronics, however. |

Apple has to continue to supply parts to california repair shops until the model is 7 years old (obsolete). So if nothing else you can try ordering from one of them. |

When the caps blow, you need a new board.
Apple has an out of warranty program for that since it's a fault with the hardware. Call them up or Apple Store it.
I think there are DIY guides if you're ok with electronics.

Unfortunately, any Repair extension programs only last till the system is vintage (5 years old) at most. So calling apple won't do you any good. Also they don't carry the parts for anything older than 5 years themselves. The only way to get official parts for anything 5-7 years old is if you live in california and go to an Apple Authorized Service Center. |

In 2009 I had one repaired free of charge when it was 4.5 years old, blown capacitors. It was sitting in my basement for a year until I found out about the replacement program.
Hivolt has replaced many capacitors himself. Hopefully he will chime in. |
